Cool idea, I'd likely post about zeolite cat litter and litter tray pee pads along with wood pulp alternatives for urine absorption. I've had a hell of a time finding alternative sources that weren't Purina or Amazon Basics.
I wish zeolite mineral cat litter systems were more popular here, it's so superior to everything else on offer.
Saw this stupid fucking headline on some magazine a coworker left behind today.
